Provide data to NBN Atlas
We want to encourage the sharing of data through the NBN Atlas, so have provided a simple guide to help you prepare your data.
PREPARING SPECIES DATA
In order to share your species data via the NBN Atlas we need your datasets in either the old NBN Data Exchange Format, or in Darwin Core format. We are supporting the use of NBN Data Exchange Format to ease this transition for our users, however, it would be preferable if you could use Darwin Core formatting as this is how the NBN Atlas holds its information.
The reason we have moved towards Darwin Core is because it is an international standard that is widely used around the world. By using this standard, we can help to make sure that the UK’s data holdings are interoperable with the data holdings of other countries, and allows an easier transition of data to GBIF.
We will be creating detailed guidance on Darwin Core uploads soon. While we are in the process of writing up NBN Atlas guidance to Darwin Core formatting, you can look at the Atlas of Living Australia guidance, which gives a lot of the required information.
Any data supplied to us in NBN Data Exchange format will be mapped to Darwin Core on entry into the NBN Atlas.
However you wish to provide your data to the NBN Atlas, you will need to be set up as a data partner first. If you gave permission for your datasets to be transferred from the NBN Gateway to the NBN Atlas, then you should already be set up as a data partner. If you are a new data partner, then please email firstname.lastname@example.org with:
- Your organisation name
- Name and email address of a contact person for the organisation
- Your logo
- A representative photo for the organisation
- Organisation address
- A link to your website
- A short (~10 word) description
Once you have created a dataset, use the NBN Record Cleaner to check there are no errors which may prevent your data being loaded into the NBN Atlas.
You will then need to email your datasets to email@example.com
Metadata is the information about your data. It describes who collected it, why it was collected, how it can be used and the methods used to collect it, amongst other things. This is important as it will provide all the information a data user needs to assess if your data are fit for their specific purpose. This information is made available to all NBN Atlas users when they view your data.
In some cases you may have concerns about misinterpretation or misapplication of the wildlife data you provide. A good metadata description can help minimise the likelihood of unintentional misuse by better informing the user and referring to sources of additional information. We ask that you use the metadata to explain the reasons behind any restrictions placed on access to or the use of your data. In this way your dataset metadata can be used to manage the understanding and expectations of users.
Find out more information on how the NBN metadata standard is compatible with other key national and international standards by downloading the Metadata standard document.
NBN ATLAS DATA PARTNER AGREEMENT
All species datasets are submitted to the NBN Atlas under the Terms of the Data Partner Agreement. This is a formal agreement between you, the data partner, and us, the NBN Trust.
It gives us the permission and assurances we need from you to hold a copy of your dataset and upload it onto the NBN Atlas.
It gives you the assurances that you need from us, including that you retain ownership over, and control the availability to, your datasets.
The agreement is comprehensive and legally necessary to formally authorise the National Biodiversity Network Trust to make your data available via the NBN Atlas.
PREPARING SPATIAL DATA
Spatial datasets include site and administrative boundaries, as well as various types of environmental data, such as soils and habitats. On the NBN Atlas, spatial datasets can be displayed by all users in the interactive map and the spatial portal. They can be used as a backdrop to maps and they support spatial searching by specific area. As tools available via the spatial portal develop the spatial layers will also be used for more complex analysis such as species distribution modelling.
Required file format and naming conventions
When preparing a spatial dataset for the NBN Atlas you should consider the following:
- Site boundaries and environmental features must have been digitised as polygons
- The preferred format is an ESRI shapefile
- Multi-part polygons are supported. If a site is defined by more than one polygon, these polygons should be grouped into a single multi-part polygon
- File name format: no spaces allowed (use an underscore), and all lower case letters
In the attribute table:
- Include a unique ID field
For example, for habitats this will usually be the habitat code; for areas or sites it could be a unique site code.
- Include a name field
This will be used to describe the feature classes in the legend and in search listings. For example, for habitats the name could be the habitat code or the habitat name. For areas or sites this will usually be the area or site name.
Metadata is required for each layer. The information should be supplied in a spreadsheet and metadata for several different layers can be supplied in a single spreadsheet, although each layer requires a separate column. This information will be used to populate the layer’s metadata table in the NBN Atlas. Please provide details for each layer as per the items in the table below and as per the metadata spreadsheet template.
The fields in the metadata spreadsheet are listed in the table below:
|Layer name||Please use the shapefile name||Layer name 1||Layer name 2|
|Title||Please provide the full name the dataset is commonly known by. It will appear in the spatial portal layer list.|
|Metadata contact organisation||Please provide the name of the dataset owner’s organisation & a link to their data discovery portal (if available)|
|Reference date||Provide date of dataset publication|
|Licence note 1||Select the Creative Commons licence to be assigned to the dataset (CC0, CC BY, CC BY-NC, OGL). If none of these options please provide details and a link to the licence description.|
|Licence note 2||Provide details of any citation required|
|Classification||Please define subject category (for use in the menu of layers|
|Scope||Describe the geographical extent of the dataset (ie UK, GB, Scotland, England, Wales or NI)|
|Notes||Use this field to provide a short description of the dataset.|
|Keywords||Keywords (such as habitats, phase 1, Scotland) for use in searches|
|More information||Please provide a link to a website that contains further metadata and/or contact details|
|Frequency of update||Provide an idea of frequency of update (eg annually, quarterly; infrequently; never; not known)|
Format of dataset legend(s)
For complex spatial layers (ie all layers except site boundaries) it would help if you could show us how you would expect the dataset legend to look in the spatial portal. You could do this by sending a link to a site that already shows the data or a PDF or image of a map where the dataset is used.
Unfortunately the NBN Atlas spatial portal does not support the creation of nested legends, which means that polygons cannot be grouped in a hierarchy (as might be useful for habitat data).
Supplying spatial layers that are accessible via a website
If the layers you wish to supply to the NBN Atlas are available for public download via your website you just need to send us the url and a list of the layers to be downloaded. We will download the layers ourselves and upload them to the NBN Atlas database.
Please ensure that the layers adhere to the formatting instructions above and that sufficient metadata is available online to enable us to complete the NBN Atlas spatial data metadata form.
